Flint PDF

Convert DOC to PDF

Bundle Word files into a clean, shareable PDF. Browser-based, no install.

  • Browser-based — no install
  • Files private to your account
  • Up to 250 MB on Pro

Drop in your Word file

Or upload any PDF, Word, Excel, PowerPoint, JPG, or PNG — we'll convert it to PDF either way.

Supported: PDF · DOCX / DOC · XLSX / XLS · PPTX / PPT · JPG / JPEG · PNG

Turn Microsoft Word documents (.docx and the older .doc) into clean, universally-shareable PDFs. Fonts get embedded, headers and footers come along, and the file looks identical on Windows, Mac, iOS, Android, and Linux.

How it works

Right in your browser, no install

Flint PDF runs entirely in your browser. Drop a file in, do the thing, get the file out.

  1. 1

    Upload your .docx or .doc

    Drop in a Word document from your desktop or cloud storage. Files up to 250 MB are supported on Pro.

  2. 2

    We render it to PDF

    Our converter (powered by LibreOffice on the server) embeds fonts, honours page breaks, and preserves headers, footers, page numbers, and tables.

  3. 3

    Open or keep editing

    Get a paginated PDF you can share as-is, or jump straight into Flint's editor to annotate, sign, redact, or merge with other PDFs.

What it's for

Built for real work

Locked-down sharing

Send a PDF version of a Word doc so the recipient can't accidentally edit it — useful for contracts, proposals, and invoices.

Cross-platform reliability

PDFs render identically on Windows, Mac, iOS, Android, and Linux. No more “the layout looks wrong on my computer” emails.

Print-ready output

PDFs are the standard format for printers and printshops — fonts and margins are guaranteed to match.

FAQ

Frequently asked questions

Does the PDF look identical to my Word file?
Yes — fonts are embedded so the result matches what you see in Word, including page numbers, headers, footers, and tables. Very obscure fonts may substitute, but the layout always stays put.
Do I need Microsoft Word installed?
No. The conversion runs in your browser plus our server — no Word, no Office, no plugins required.
Does it support both .doc and .docx?
Yes. The older .doc format works alongside modern .docx; we'll detect the right one from your file.
Is it free?
You can try the conversion in the browser without an account. Downloading the resulting PDF requires Flint Pro.
Are my files private?
Yes. Files are processed only for the conversion you trigger and stay tied to your account. We don't share them with anyone.
What's the maximum file size?
Flint Pro accepts Word files up to 250 MB.
Can I convert PDF back to Word later?
Yes — our PDF to Word converter turns any PDF back into an editable .docx with tables and images preserved.
